WINDOW BLIND.

Application med January 28, 1925; Serial No. 5,388.

This invention relates to window blinds and has for an object the provision of an improved blind of the Venetian type which may be readily raised or lowered, or otherwise adjusted within a window frame or opening.

Another object of the invention is the provision of a blind which in addition to the above and other advantages is simple in 'construction, ready of adjustment and which will present an attractive appearance:

With the above and other objects in view,

the invention further includes the following novel features and details of construction, to be hereinaftermore fully described, illustrated in the accompanying drawings and pointed out in the appended claim.

In the drawings Figure 1 is an elevatlon showing a window frame with the blind in lowered position and the slats separated. 1

Figure 2 is a vertical sectional view of the same. i

Figure 3 is 'a view similar to Figure 2 with the slats partly closed.

Figure 4 is a plan view of one of the slats Figure 5 is an enlarged fragmentary sectional view. J Figure 6. is a detail perspective view of one of the coupling members.

in like characters of reference derote corresponding parts, the reference character 10 indicates a window frame within which is positioned vertically disposed spaced guides herein illustrated as chains 19. The

opposite ends of the chains are secured to} the top and bottom of the frame as indicated -at 12 and the chains are spaced at relatively short distance from the opposite sides of the window frame. v

Slidable upon the chains 11 are slats 13 and 'for this purpose theseslats are provided withopenings 14 through which the chains 11 pass. Positionedvwithin the openings 14 are anti-friction devices or pulleys 15, the latter being mounted upon reduced portions 16 provided in plates 17 the opposite ends of these plates being secured to the slats as shown. The slats are thus capable of vertical movement along the chains 11, the latter passing through the slots adjacent one of their longitudinal edges. Passing through openings 18 provided in the slats 13 is a cord or cable -19, fastening means 20 serving to hold the slats relatively spaced upon the cord or cable. This cord. or cable 19 extends through guides or eyes 21 secured tothe top of the window frame.

-By pulling upon one end 'of'the cord or cable 1 9, the slats may be raisedto theto'o of the window. frame. the weight of the slats causing thel'jlattei'i to descend along the chains when thejc'ord is released. Due to the relative locations of the openings 14 and 18 through which the chains and cord pass, the slats may be' moved pivotally upon the chains to an open or closed position.

The inventionis susceptible ofvarious changes in its form, proportions and minor details of construction and the right is here'- in reserved to make such changes as proper- 1y fall within the scope of the appended 0 mm.

Having described the' invention what is claimed is z-' Ina window shutter, the pombination with a frame, of spaced vertically disposed chains f Referring to the drawings in detail where-' having their opposite ends secured to the top and bottom of the frame, slats provided with transversely disposed elongated openings adjacent their ends, plates secured on y the slats near the ends, thereof and provided with, reduced portions positioned transversely across the openings in the slats, "pulleysjournaled upon the reduced portions and engaging through certain-1 opposite links of the chains, wherebythe rollers may have free movement as the slats are inclined owa-rd' closed positions, and a cable extending through and secured to the slats for operating the slats toward closed positions, and guides at the top of the frame for the pas sage of the cable.
